The evolution of PC games hasn't been largely in the way they're controlled, but in depth and realism of the content. Although, I have to concede that there has been little progress since the nice little mini revolution between 1998-2000, PC games still are pushing realism and depth in ways that consoles just don't. Just look at the visuals in a game like Crysis, or the complexity of a game like Sins of a Solar Empire. Its quite an evolution from Doom and Dune.
There was a long gap between when Ocarina of Time revolutionized how an adventure game could be controlled on a console, and the release of the Nintendo Wii... but control has always been a more important feature on console games than PC games. With the current emphasis on Massively Multiplayer, and community based PC games, I don't see control schemes straying away from a keyboard and mouse anytime soon either.
This isn't an Apple's to Apple's comparison. PC gaming and Console gaming are pretty different experiences. PC gaming have revolutionized plenty, thank you.
